Sena 50R battery life
My 50R is about 2 years old,it gets a full charge,but after about 20 minutes,with the power off,the battery is down to 73%. What could be the issue? bad battery,or is something else causing it to drain prematurely??

Hey Norman!
there are a few potential causes to consider. A likely culprit is a deteriorating battery. Lithium-ion batteries, like the one in your 50R, naturally lose capacity over time, and after two years, it might not hold a charge as efficiently as it once did. However, it’s also worth checking for other possible factors.
Sometimes, background features like mesh intercom or Bluetooth standby could still draw power, even when the device appears to be off. Ensure that the device is completely powered down and not in a low-power mode. Another possibility is a firmware glitch. If your unit isn’t on the latest firmware version, the battery management system might not be functioning optimally. Updating the firmware might help resolve the issue.
If these steps don’t solve the problem, it’s likely that the battery itself needs replacement.

Hey Norman,
It sounds like you're experiencing unusual battery drain on your Sena 50R after it has been fully charged. Here are some possible causes and troubleshooting steps to help you address the issue:
1. Battery WearNormal Battery Aging: Since your Sena 50R is about 2 years old, it’s possible the battery has started to degrade. Lithium-ion batteries, like the one in your 50R, lose capacity over time and after many charge cycles.
A decrease in battery life, especially after 2 years of use, is common. The 73% drop in 20 minutes could be an indication of a battery that’s no longer holding a charge effectively.
2. Firmware Issue
Outdated Firmware: Sometimes, the firmware can cause abnormal battery behavior. A bug or issue in the firmware could cause the battery to drain faster than normal.
Make sure your Sena 50R has the latest firmware by checking with the Sena Device Manager or Sena Connect app.
3. Power-Consuming Settings
Background Processes: If the Sena 50R has any features running in the background (like Bluetooth pairing with devices or automatic voice commands) even when powered off, it might be causing unnecessary battery drain.Bluetooth or mesh mode can sometimes stay active in the background, which would lead to faster battery depletion.
Try turning off all other features (e.g., mesh intercom or Bluetooth connections) when not in use, and make sure the 50R is fully powered off.
4. Battery Calibration
Battery Calibration: Sometimes, the battery indicator may become miscalibrated, leading to inaccurate readings. This means the battery might not actually be draining as quickly as it seems, but the device is showing a lower percentage.
Try discharging the battery completely (letting it drain until the device shuts off) and then recharge it fully to 100%. This can help reset the battery’s calibration and provide a more accurate reading.
5. Check for External Factors
Environmental Factors: High or low temperatures can affect battery life, causing it to drain faster than usual. Ensure you're charging and using the Sena 50R in moderate temperatures.
Cold temperatures in particular can cause lithium-ion batteries to behave poorly.
6. Faulty Power Management Circuit
Internal Hardware Issue: If none of the above steps resolve the issue, it could be a problem with the 50R's internal power management circuit. This could be causing incorrect readings and abnormal battery drain.
In this case, you may need to contact Sena support for further assistance and possibly a replacement battery if the device is still under warranty.
7. Battery Replacement
If it’s determined that the battery has degraded significantly, it may need to be replaced. Sena can offer battery replacement services, but this may require sending the unit in for repair.
Next Steps
Update firmware to ensure it’s not a software issue.
Calibrate the battery by fully draining it and charging it to 100%.
Turn off any unnecessary features when not in use.
Check for external temperature impacts.
If the issue persists, contact Sena support for potential battery replacement or a repair evaluation.
